replacement of a damaged motor with a larger motor when a suitable motor is missing;

reduction of production.

In the oversizing of the induction motors we find several disadvantages like elevation of the cost, greater weight and volume of the engine, as well as the reduction of the power factor, reduction of the efficiency, although some motors have their maximum efficiency to 75% of their nominal load.

Another disadvantage is a higher starting current, resulting in higher installation cost and protection.

In times when it is necessary to use energy efficiently, the aspect of oversizing should take into account technical and economic analysis. Studies show that oversizing does not always correspond to greater energy losses.
